Definitions
- the present invention relates to a water distribution system having an automatic hot water pasteurization procedure.
- SE 1750766-6 there is disclosed a method for hygenisation of a device intended for recycling of water, said device comprising a flow path for recycled water, a fresh water inlet, a recirculation water inlet and a recirculation water outlet, a user outlet, a heater and a filter, said method comprising performing the steps of heating water in the heater; and flowing heated water from the heater back to the filter for decontamination of the filter and other components in the flow path for recycled water.
- the present invention is directed to providing a water distribution system, and method therefore, which is arranged to perform an automatic hot water pasteurization procedure with high reliability and efficiency.
- a water distribution system comprising a water supply, a heating source, at least one temperature sensor, a flow path for water with a user outflow, and a control unit for operation of the water distribution system, said temperature sensor being connected to the control unit, wherein the control unit also is connected to at least one presence sensor arranged for the detection of presence of a human or animal body in physical proximity to the user outflow and/or in an outflow direction area from the user outflow and wherein the control unit is arranged to drive a hot water pasteurization procedure of at least a portion of the flow path and out from the user outflow based on a response or an indication of no presence of a human or animal body in physical proximity to the user outflow and/or in an outflow direction area from the user outflow.
- the present invention is directed to a water distribution system comprising a presence sensor, where said presence sensor acts as a safe guard so that there is no risk for presence of a human or animal body once a hot water pasteurization procedure is performed in the water distribution system and where hot water then is flown out from a user outflow.
- the expression“animal body” this may e.g. refer to pets.
- the expression“in physical proximity to the user outflow and/or in an outflow direction area from the user outflow” implies in any position where there is a risk to be exposed to hot water flowing out from the user outflow.
- US 2011/0042470 discloses a user activated hot water heater and control system for processing hot water to hot water output locations, e.g. faucet, shower, or the like.
- the temperature of the hot water delivered may be adjusted to a predetermined value determined by a user signature constructed from a potential user physical attributes such as height, weight, and the like.
- Detection of a unique individual user or general category user may be accomplished via the use of at least one physical attribute sensor.
- the physical attributes of the potential hot water user detected are primarily based on the user's height, weight, or combinations thereof.
- US 201 1/0042470 differs in several points when being compared with the system according to the present invention.
- the sensors provided in the system US 201 1/0042470 is being used to detect certain parameters to drive a pre-heating sequence, and not as a safe guard and blocker for a hot water pasteurization procedure according to the present invention.
- the systems as such are very different, where the water distribution system according to the present invention comprises several key elements, e.g. other sensors, which are not existing or implemented in a similar way in the system according to US 201 1/0042470.
- said at least one presence senor is a motion sensor, an IR sensor, a radar sensor or a combination thereof, preferably a radar sensor or a radar sensor combined with another sensor. It should be mentioned that combinations of different sensors are also possible.
- said at least one presence sensor is combined with at least one other sensor. It should be noted that several presence sensors are also possible according to the present invention. As an example, any type of motion sensor may be combined with a IR sensor. As such, effective detection may be possible both in light and in the dark.
- said at least one presence sensor is a radar sensor.
- a radar sensor combined with another sensor is also fully possible to incorporate according to the present invention.
- the water distribution system according to the present invention may be any type where hot water may be used and where people or animals are intended to use the system and water, e.g. in houses, hotels or the like. Also recirculating systems are of great interest for the present invention.
- the water distribution system is a water recirculation system.
- the water recirculation system is a recirculating shower.
- the presence sensor or sensors may operate as a direct blocker of the system so that it cannot be operated. Furthermore, also a type of alarm function may be linked to the presence sensor. Most preferred is that the control unit is directly connected to the presence sensor. Therefore, according to one specific embodiment of the present invention, said at least one presence sensor is connected to the control unit.
- the presence sensor may then simply function as a safe guard in the control unit. When the presence sensor does not indicate that there is a presence, then the control unit is free to perform a hot water pasteurization procedure in the water distribution system. When there is a presence, however, then the presence sensor sends a signal to the control unit and the control unit then knows that it cannot drive a hot water pasteurization procedure in the system.
- a flow control unit is connected to the control unit.
- a flow control mechanism in a system according to the present invention is possible and of interest as the temperature of the water in the system is measured and may be controlled.
- these two parameters that is temperature and flow, or volume linked to time, are the factors of importance when ensuring a disinfection of the flow path or at least part of the flow path. Therefore, according to the present invention it is possible to control both of these parameters in the control unit.
- the flow control unit is a flow meter located in the flow path. Such a flow meter may then measure the flow and send this information to the control unit.
- a timer unit is connected to the control unit. The timer unit then functions to set a suitable time for exposure of the tube of the flow path to hot water during the hot water pasteurization procedure. As may be understood from above, if temperature, flow and also exposure time may be set in the control unit, then all important aspects of the hot water pasteurization procedure may be fully regulated by the control unit.
- control unit is also connected to one or more other types of sensors.
- the other types of sensors is at least one sensor which measures water quality.
- This sensor may then also be linked to the control unit. This connection may be based on measurement and then operations in the system.
- the water distribution system is a water recirculation system intended for recycling of water or discarding of water not suitable to recycle, said water recirculation system comprising a flow path for recirculation, at least one water treating unit, and a sensor unit arranged for measurement of at least water quality, and wherein the sensor unit is connected to the control unit which decides if water should be recycled or discarded in a point of separation based on the measurement of the water quality, said water recirculation system also comprising a heating source and a user outflow arranged at the end of the flow path for recirculation, and wherein the control unit is arranged to drive a hot water pasteurization procedure of at least a portion of the flow path and out from the user outflow based on a response or an indication of no presence of a human or animal body in physical proximity to the user outflow and/or in an outflow direction area from the user outflow.
- the control unit has several key task operations.
- One such key operation is to determine if water should be recirculated in the system of should be sent to another separation or sent to waste.
- Another one is to drive a hot water pasteurization procedure and to use a presence sensor as the safe guard to ensure that no person or animal is present when hot water is flown through and out from the user outlet.
- the present invention is also directed to a method. According to one embodiment of the present invention there is provided a method for performing a pasteurization procedure in a water distribution system according to the present invention, said method comprising
- a flow control unit is connected to the control unit and wherein the method comprises controlling the flow of hot water during the pasteurization procedure.
- a timer unit is connected to the control unit, and wherein the timer unit sets the intended time for flowing hot water based on the temperature measured in the temperature sensor.
- control unit is suitably connected to both a flow control unit and a timer unit.
- the water distribution unit comprises a flow control unit being connected to the control unit and a timer unit being connected to the control unit, and wherein the method comprises controlling temperature, flow and residence time of the hot water during the pasteurization procedure.
- the system and method according to the present invention provides a pasteurization solution which is both free from the need of additional chemicals and where no additional maintenance is needed.
- the present invention may provide a system where the entire hot water pasteurization procedure may be regulated with reference to temperature, water flow and water amount being used and the exposure time. These features also enable that the flow rate being used may be reduced as long as the temperature and exposure time are high enough to ensure a strong hot water pasteurization.
- a water distribution system 1 may be connected to a water tap in a sink.
- the water distribution system 1 comprises a water supply, a heating source 100, at least one temperature sensor, a flow path for water with a user outflow UO, and a control unit for operation of the water distribution system 1 , where the temperature sensor is connected to the control unit.
- the control unit is also connected to at least one presence sensor PS arranged for the detection of presence of a human or animal body in physical proximity to the user outflow UO and/or in an outflow direction area from the user outflow UO.
- the presence sensor PS may e.g. be arranged above the water tap so that the sensor PS may detect any type of presence of hands or the like in the sink.
- control unit is arranged to drive a hot water
- pasteurization procedure of at least a portion of the flow path and out from the user outflow UO based on a response or an indication of no presence of a human or animal body in physical proximity to the user outflow UO and/or in an outflow direction area from the user outflow UO.
- the water distribution system 1 is a water recirculation system 1 in the form a recirculating shower.
- the water recirculation system 1 is intended for recycling of water or discarding of water not suitable to recycle.
- the water recirculation system 1 comprises a flow path for recirculation 50, at least one water treating unit 6, which may be e.g. a filter or a UV unit or something else, and a sensor unit 7 arranged for measurement of at least water quality.
- the sensor unit 7 is connected to the control unit (see dotted lines) which decides if water should be recycled or discarded in a point of separation 30 based on the measurement of the water quality.
- the water recirculation system 1 also comprises a heating source 100 and a user outflow UO arranged at the end of the flow path for
- the control unit is arranged to drive a hot water
- pasteurization procedure of at least a portion of the flow path and out from the user outflow UO based on a response or an indication of no presence of a human or animal body in physical proximity to the user outflow UO and/or in an outflow direction area from the user outflow UO.
- the heating source 100 and the water treating unit 6 may be one and the same unit, i.e. only hot water is used to treat the water.
- the water treating unit 6 may also be in a combined unit, such as a combined UV and heater unit.
- the water treating unit 6 may also be in a separate unit, such as shown in fig. 2. In this case it is in the form a filter 6.
- the heating source 100 may be complemented with several heating units, of same type or different.
- One possible solution is as a heat exchange arrangement.
- other types of external heating sources may be used, such as solar panels, LP gas etc.
- hot water is used for heating, also in the case where solar panels or other heating sources are used. In such cases water is heated by the external source, and is then used in the water recirculation system 1.
- the sensor unit 7 may in fact comprise several sensors. Such sensors may be positioned at different places in the system. In the embodiment shown in the figures, one or several may be positioned in a drain 300 where the point of separation 30 may be located.
- fresh cold and hot water enters the system via a mixer arrangement.
- the sensor PS may e.g. be arranged in the bath room ceiling. It should, however, be noted that there may be several suitable positions, as long as it is possible to detect presence in a flow direction out from the user outlet or close proximity thereto. The positioning used is also dependent on the type of shower installation. As another example, the shower may be operated by a user panel and this user panel may also have an integrated presence sensor PS. It should also be noted that the presence sensor may in fact be a sensor which detects something which in turn is a probable indication of presence. As one possible example, the presence sensor PS or at least one sensor PS in a combined PS system may be a sensor positioned to detect if the shower door is opened / closed.
- Any type of opening or closing then is a detection of presence. This may function together with other sensor solutions. This also implies that for the detection of presence of a human or animal body in physical proximity to the user outflow (UO) and/or in an outflow direction area from the user outflow (UO) a presence sensor does not have to detect this directly but may detected this both indirectly and/or directly.
- One other sensor solution possible according to the present invention may be to also combine the present invention with so called smart home solutions.
- a smart home system knows that no one is at home, or that all possible users are positioned at a distance from unsafe places, then a hot water pasteurization procedure may be performed.
- Such a smart home solution may also be combined with one or more presence sensors PS as described above. To combine the different sensors like this may imply that a simpler presence sensor PS may be used according to the present invention.
- the senor PS may be only one unit or several, possibly also of different types.
- the system 1 comprises both a IR sensor and another type of motion sensor.
